Why equilibrium constants matter
Why equilibrium constants matter

A reversible reaction can proceed in both directions. In a closed system, dynamic equilibrium is reached when the forward and reverse reactions continue at equal rates, so the concentrations stop changing.
Step-by-step lessons on Eduqas A Level Chemistry Equilibrium constants. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
